Rare mathematics books in the American University Library, American University, November 21, 2008.

Ferdinand Hassler's Fabulous Library, Canadian Mathematical Society, Ottawa, December 6-8, 2008.

Ferdinand Hassler came to the United States in 1805 with a library of several thousand technical books. Sadly, poverty forced him to sell many of them. In 1825, the United States Military Academy Library purchased 405 books from him. Unfortunately, no list of those books has been found and he did not write his name in his books, so they cannot be definitely identified. By comparing library catalogs and correspondence for other book purchases, I will conjecture about which treasures in the West Point Library came from Hassler.
